To call attention to the environmental toll of fossil fuel consumption, a group of motorbikers/performance artists in Yogyakarta, Indonesia strapped weighty shrubbery to their heads and tooled around town. This is a smashing look for the incognito Hell's Angel looking to masquerade as office foliage. Explains the Szpilman Awards, which celebrate ephemeral artwork:

Sara Nuytemans & Arya Pandjalu call for a bike gang to drive through the city of Yogyakarta. The bikers wear special designed helmets, weighty and beautiful, stuffed with soil and planted with a tree. The performance is meant as a homage to this very green city and also a wink to the idea for direct carbon dioxide compensation.
